1、最近在使用TI的TMS320DM6437处理器，安装完CCS3.3后，又安装了DVSDK.可是发现PSPdriver下的example无法编译通过，经过几天的研究，终于发现了一些环境配置上的细节，整理出来供大家分享。1.安装CCS3.3，推荐安装默认路径“C:CCSt io_v3.3”,安装时按照提示进行，对于TI Emulator driver 选项可以取消不安装，在有些XP系统上，如果不取消此项的安装，会在安装结束后会死机，原因不明。2.完成CCS3.3的安装后，再安装DVSDK,推荐安装默路径C:dvsdk_1_11_00_00,安装过程为会提示安装最新的DSP/BIOS，可以选择不装，
2、如果安装了，会在CCS3.3目录中多一个子目录bios_5_3x_xx（可能与CCS3.3自带的DSP/BIOS版本不同,x为版本号，根据具体情况有所不同）3.以上两个软件安装完成后，要设置系统环境变量，供编译工具链使用。具体参数设置如下（如果是在默认路径上安装的话）BIOS_INSTALL_DIR C:CCSt io_v3.3bios_5_31_08BIOSDVSDK_INSTALL_DIR C:dvsdk_1_11_00_00BIOSUTILS_INSTALL_DIR C:dvsdk_1_11_00_00biosutils_1_00_02BSL_EVMDM6437_INSTALLDIR C

4、dc_2_95_024.设置完成后，CCS3.3/bios_1_xx_xx下的例子都有可以编译和运行了。但是C:dvsdk_1_11_00_00pspdrivers_1_10_00下的例子还不能编译通过。以目录C:dvsdk_1_11_00_00pspdrivers_1_10_00packagestisdopspdriverssystemdm6437biosevmDM6437 rt下的例子说明如何配置，使example能正常编译。5.用CCS3.3找开工程文件dm6437_evm_ rt_st_sample.pjt，这时如果打开dm6437_evm_ rt_st_sample.tcf文件会出错
5、，选择dm6437_evm_ rt_st_sample.tcf，右键选择DSP/BIOS config-text edit,打开文本模式，找到utils.importFile(ti/sdo/pspdrivers/system/dm6437/bios/evmDM6437/ rt/dm6437_ rt0.tci);替换为utils.importFile(dm6437_ rt0.tci);保存。这样这个脚本文件就能正常运行了。但是这时编译会提示找不到一些文件。这是因为XDC工具读取的路径文件中的路径没有设置设置方法如下：打开C:dvsdk_1_11_00_00pspdrivers_1_10_00pa
